392 ;; operate on a given output string.

396 ;; returns a complete table of contents, `org-ascii--list-listings'
397 ;; returns a list of referenceable src-block elements, and
398 ;; `org-ascii--list-tables' does the same for table elements.
400 ;; The third category includes general helper functions.
401 ;; `org-ascii--build-title' creates the title for a given headline
402 ;; or inlinetask element. `org-ascii--build-caption' returns the
403 ;; caption string associated to a table or a src-block.
404 ;; `org-ascii--describe-links' creates notes about links for
405 ;; insertion at the end of a section. It uses
406 ;; `org-ascii--unique-links' to get the list of links to describe.
